How do I use a gravatar to offer site comments?
I'm in Level 5 Training and I want to offer 10 site comments as per the training. When I press "submit", it won't go unless I enter a Gravatar email address. I signed up and activated one at Word Press, but I don't know how to use it to submit comments. If you can understand my ramblings, please give me some guidance. It is greatly appreciated.
